Recommended Use  

This reliable real-time maritime information gives commodity traders in the oil and gas business, fleet owners and operators, environmental agencies, finance industry and marine insurance companies piece of mind with accurate location of highly valuable assets and cargo on the sea.

Benefit from TimeCasted AIS data in standard configuration:

  • Know ship arrivals in advance and verify other sources such as crew reporting
  • Predict where a ship will be in the near future
  • Discover if a ship is making unauthorized port calls
  • Maintain compliance with Marine Insurance covenant
  • Track in real-time own and/or competitor’s fleet
  • Identify when a ship is attempting to hide by disabling its AIS

Simplify your ship and cargo tracking with advanced configurations of TimeCaster:

  • If you do not want to deal with cryptic AIS messages, ask us about subscriptions to customized reports.
  • If you need to use data from multiple AIS sources, we can fuse them for you and TimeCast the aggregated stream.


More accurate and less ambiguous AIS data with TimeCaster
TimeCasted data increase maritime awareness, since they are more accurate than raw imagery and less ambiguous due to Doppelganger indentification. Raw AIS data provides average accuracy with errors of over 100 nautical miles because each ship position can take many hours to update. TimeCaster provides 10-minute position updates for every ship with an accuracy of 10-30 miles so you always know where the ship is now. Every day around 9.000 identity codes (MMSI numbers) are used by more than one ship, either by chance or on purpose. TimeCaster resolves this problem by tracking each ship separately even if another ship is sharing the same MMSI.


Product Description 

Based on the real-time AIS data the TimeCaster service predicts the current and future positions of all ships globally as of a common time (“now” or in the near future).

  • Improved accuracy: TimeCaster improves accuracy of the actual and predicted ship positions by 4 to 17X compared to raw satellite and terrestrial AIS data. Raw AIS data position errors range from 75 - 160 nmi, while TimeCaster increases the accuracy to 10-30 nmi through the predictive analytics algorithms.
  • 10-Minute position updates on all ships globally: The service updates every ship position every 10 minutes. Other technologies only provide positions with an average age of 2+ hours and with age spreads ranging 10 minutes to more than 24 hours. TimeCaster also predicts all ship positions several hours into the future.
  • Less ambiguous: The service automatically detects, tracks and predicts locations for Doppelgangers. Doppelgangers present a significant issue: 9,000+ MMSI’s (i.e. ship identity numbers) are used by more than one ship every day. The existence of a Doppelganger can cause a ship to disappear from a display, makes the static (e.g. name, IMO number) and voyage (e.g. destination) data ambiguous and makes track histories unreliable.
  • Easy to integrate: TimeCaster provides a data stream that can directly feed your existing display and analytics systems. It supports NMEA4, OTH-Gold or customized data interface standards.
  • Optional alerts: You can receive alerts for ships that stop transmitting for an unusually long time.
